VAIL, Colo. (AP) - When Jack the dog ran into trouble last month, he couldn't have had a better man around to help. Physician Dave Karli and his dog were out for a walk near their home in Edwards while a father and son were playing catch with a baseball nearby.

Jack, a Weimaraner mix, went to get some baseballs on the ground and tried to get several in his mouth.

One went down his throat and got stuck in his airway. Karli said he reached his hand down Jack's throat and was able to remove the ball. He was bitten in the process.

After the ball was removed, Jack remained passed out. Karli did CPR on his dog for about 15 to 20 seconds until Jack regained consciousness.

Chris Roth, a veterinarian at Eagle-Vail Animal Hospital, said he doesn't see a lot of owners having to do CPR on their dogs.
